Breaking changes only related to configuration and not the Updater API

Bits Downloader now handles broken downloads gracefully (this is a fix to the original implementation)

UpdaterTask serialization fixed. There was a bug on the net 1.1 version of UAB related to the partial update scenario. When some files were removed from the manifest, the UAB serializes the UpdaterTask with the original version of the files. This caused the ApplicationDeployProcessor to fail.Partial update scenario fixed.
